' the wires, thus causing. short circuits with their attendant dangers.

Y My means of accomplishing the foregoing object may be more readilyunderstood by having reference to the accompanying drawings, in which' AY Fig. 1 1s a vertical, sectional view of my.

improvement; and t Fig. 2 1s a side elevat on of the same. Similarreference numerals refer to S111l1 lar parts throughout the entiredescription.

As shown in the drawings, the fixture I stem 1 extends from the fixture(not shown),

and has mounted atits outer end 2, my 1mprov-ed housing 3. This housingis formed of a cylindrical t be in which is located a standard socketshell 4 which is provided with the usual standard sleeve 5 formed ofsuitable insulating material. Within the tube 3, at the point ofentrance of the stem 1, I mount a section of tubing6 which has a verythick or heavy wall, which is provided with 'a threaded opening 7, intowhich the threads on the end of the stem 1 maybe screwed. Y 'To thoseskilled in the art, it will be apparent from the foregoingdescription'that this construction provides a thickness for the supportof the housing, which is not to be found inthe ordinary housings, andhence possesses unusual strength at this point.

The lower end 8 of the tube 3 is closed by a disc 9 having a centralaperture 10 which forms a convenient pull in box for the electric wires(A) and in which is mounted an upwardly extending stem 11 formed on aplate 12 and fitting the threaded portion of the hickey 13 ofthe socketshell 4;. The rotation of the socket 4 is prevented by means of a smallscrew 14 which passes through a threaded hole 15 and extends into a hole16 formed in the disc 9, though any other suitable means for thispurpose may be employed.
